Type Alias Primitive

Represents the set of all JavaScript primitive types. Includes bigint, boolean, number, string, symbol, null, and undefined.

These are the seven primitive data types in JavaScript, as opposed to objects which are reference types. Primitive values are immutable and are passed by value.

Example

type P1 = Primitive; // bigint | boolean | number | string | symbol | null | undefined

const checkPrimitive = (value: unknown): value is Primitive => {
  return value !== Object(value);
};

checkPrimitive(42);       // true (number)
checkPrimitive("hello");  // true (string)
checkPrimitive(true);     // true (boolean)
checkPrimitive(null);     // true (null)
checkPrimitive({});       // false (object)
checkPrimitive([]);       // false (array/object)
